Hey Sparkle: The volatile nature of human nature, according to me, are as follows 1. Selfish 2. Sloth 3. Gluttony 4. Hedonist 5. Pride (where falls the notorious trio, as Raybati pointed, Id, Ego, Superego) 6. Vulnerability Well, above all- "To be or not to be that is the question....!!!" So long as you follow your heart and head, these very volatile nature should have no effect or whatsoever to any human nature. EZ with life ya' all.... Quest
